ping <EMS CLOUD>

2) Try running the following command in one test PC having the issue, run the command via PowerShell>Run as admin:

C:\Program Files\Fortinet\FortiClient\FortiESNAC -c REG_UNREGISTER

3) Verify if the endpoint unregisters, if it does, generate a new invitation code and try to join the EMS Cloud again.

Be sure the remote registry is running:

Use cmd as admin, navigate to FortiClient install path "C:\Program Files\Fortinet\FortiClient\" and execute:

FortiESNAC -c REG_REG_TO_CLOUD -a <INVITATION CODE>
